Application filed June 20,1898. Serial No. 683,983. (No model.)

To al whom it may concern.-

Be it known that I, SIMON GOLDNER, a subject of the King of Roumania, residing at New York, in the 'county and State of New York,have invented new and useful Improvements in Diamond and Mounting Gages and Ring-Gages,'of which the following is a Speci- By means of this invention diamonds, as also their mountings, can be readily gaged, as set forth in the following specification and claim and illustrated in the annexed drawings, in which- Figure l isa face view of a gage. Fig. 2 is an edge view of Fig. 1.

The gage or scale is shown comprising a base or sections 1 and 2, jointed or pivoted at- 3, so as to be folded up when not in use or to The gage is provided with rings 4, the exterior as Well 'as the interior of which is adapted for gaging. A suitable scale on the base will indicate weightas, for example, that of a diamond 12'fitting the largest ring, as two-and-a-quarter karats; and that a mounting or claws 13, fitting or Slipping about the exterior of this ring, is adapted for setting a stone of four karats. Each ring being thus provided with a double scale or numeration will serve the double function of a diamond-gage as also of a gage for the mounting or setting of a diamond. The rings being mounted clear of oneanother, their exterior is left free for gaging. Each ring is shown carried by a supporting-arm 5, proj ecting from the base and made to engage its gaging.

ring at one spot or point, so as to leave practically the entire exterior of the ring clear for The base has one of its sections provided with a scale6 for gaging rings. One of the jaws '7 and S is movable or sliding and connects by rack 9 with hand or index 10, so

as to actuate or move the latter over the scale. A returning-spring 14 normally holds the index at the starting-point, and as a smaller or larger ring 15 is slipped over-the jaws the movable jaw 7 is moved more or lessto carry the index 10 to a lower or higher number on scale 6.

The index 10, it is seen, is formed integral with or has its pivot or hub portion formed as a pinion 11 for the mesh of rack 9.

What I claim as new, and desire to Secure by Letters Patent, is. I

A gage'comprising a base having a series of arms each 'of which carries at its outer ex- 5 5 tremity a ring the interior and exterior of which are adapted for gaging, said arms en gaging the rings at one point and supporting them clear of each other, the respective internal, and externalmeasurements ofeach 6o' ring being denoted on the base opposite thereto, substantially as described.

In testimony whereof Ihavehereunto set my hand in the presence of two subscribing witnesses. p SIMON GOLDNER.
